>>66093491/12 cars are a lot bigger than most people would want to buy. Several years ago, Revell made this Shelby GT500 model kit which you may still be able to find on eBay, and as I said in the previous thread (
>>6587572), there are also radio controlled cars available on Amazon. However, none of them have openable doors, so if you want to put figures inside them you'll have to buy only convertibles, or else try to modify the model kit so that the doors open.
